Abstract (en)
An illumination system includes an illumination unit (10) and a thermoelectric conversion module (30). The illumination unit (10) includes a light source (12), and a reflection plate (11) capable of radiating heat from the light source to the outer circumference of the plate. The thermoelectric conversion module includes lower and upper substrates (31A,31B), lower and upper electrodes (32A,32B) provided on the facing surfaces of the lower and upper substrates, and thermoelectric elements (33) disposed between the lower and upper electrodes (32A,32B). The lower substrate (31A) of the thermoelectric conversion module (30) is fixed to the reflection plate via a heat transfer member (21). The upper substrate (31B) of the thermoelectric conversion module (30) is connected via a heat releasing path member (41) to a support member (51) (heat absorber) having a thermal conductivity higher than that of air.
